Sutera plant named ‘Sutcatrwhi’

ABSTRACT

A new and distinct variety of  Sutera  plant particularly distinguished by its white flowers, earliness to flower, thick stems, heat tolerance and a growing habit that is spreading and trailing.

Latin name of the genus and species of the plant claimed: Sutera diffusa.

Varietal denomination: ‘Sutcatrwhi’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Sutera, botanically known as Sutera diffusa.

The new cultivar is propagated from cuttings resulting from the cross of ‘B22’ and ‘B24’. ‘B22’ is a white flowering Sutera having a spreading, trailing habit. ‘B22’ is not commercially available and is not known by any synonyms. ‘B24’ is a white flowering Sutera having a compact habit. ‘B24’ is not commercially available and is not known by any synonyms. Neither ‘B22’ or ‘B24’ has been patented.

As a result of this cross the present cultivar was created in 2000 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and Sarrians, France over a three year period. It has been found to retain its distinctive characteristics through successive propagations, and this novelty is firmly fixed.

This new Sutera plant is an annual in most climatical zones in the US, only in zones 9 and 10 it is a perennial plant.

SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

-   -   a) Exhibits white flowers;     -   b) has thick stems;     -   c) exhibits a spreading and trailing growth habit; and     -   d) is very resistant to hot conditions.

DESCRIPTION OF THE DRAWING

This new Sutera plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Sutera. The data that define these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 15 week old plants, blossomed under natural light in a greenhouse and grown in 11 cm containers. Colour readings were taken in the greenhouse under ambient light. Colour references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
